Mickelson's grandfather, Al Santos, grew up in Monterey and had to leave school in the fourth grade to go to work. He was a caddie at Del Monte Golf Course, and was among the first caddies to work at a new golf course that opened in 1919 called Pebble Beach.

"He always felt poor, and there were many days where he wasn't able to eat," Mickelson said.

Santos kept in his pocket a silver dollar from 1900 that he never spent. Instead, he rubbed the coin whenever he felt poor, a small comfort to know that he had money. He died in 2004, just months before Mickelson won the first of his four majors.

"I have that silver dollar today, and I've used it during the AT&T Pebble Beach Pro-Am as a marker, and will continue to do so," Mickelson said in a conference call last month. "And he used to work, I believe, for 35 cents a bag around that course. And it's just a cool feeling to have the money that he cherished and also to see what we are now playing for in prize money, and how far the game of golf has come. It's a great reminder for me."

With his win last week, Mickelson is approaching $69 million in career earnings on the PGA Tour.

Mickelson said his grandfather gave him an old Krugerrand that he keeps, along with some 50-cent pieces Mickelson's father gave him, and military coins he has collected over the years. But that 1900 silver dollar is special.

"His silver dollar is the one I prefer to mark with, especially in the competition at Pebble Beach," Mickelson said.

SLOW PLAY: Golf is starting to get serious about the pace of play _ at least officials are talking a good game.

One week after PGA Tour commissioner Tim Finchem announced a comprehensive study on pace of play, the USGA said it has started its own study that is looking at four areas _ golf course design, the way the course is set up (green speed, length of rough), managing tee times so a golf course is not crowded and education.

"Pace of play has been an issue for decades, but it has now become one of the most significant threats to the game's health," USGA president Glen Nager said. "Five-hour plus rounds of golf are incompatible with life in modern society, where there are many alternative forms of entertainment and sport that fit more comfortably into the compressed time that we have available for recreation and relaxation.

"Pace of play is a problem, for both men and women, at the professional level, the elite amateur level, and the recreational level," he said. "Now, more than ever, the golf community needs to act."

So much of slow play comes from anecdotal evidence, though USGA executive director Mike Davis mentioned some empirical evidence. He said officials at Pinehurst have determined that it takes 30 minutes longer to play for each foot of speed on the Stimpmeter _ the difference between greens at 12 and 13, for example.

"I'm not sure we have all the answers," Davis said. "We're not the only ones doing it. But I sense that the industry, if it really tries, can make a dent on this."

Davis also said the USGA wants to promote more 9-hole rounds and different formats, such as match play or the Stableford system, to move things along.

GANGNAM STYLE: James Hahn is off to a solid start in his rookie season on the PGA Tour, and he's already made a name for himself.

All because of one birdie. And one dance. On one very famous hole.

Hahn heard some of the chatter about how to react with a birdie on the 16th hole of the Phoenix Open, the rowdiest hole in golf. He thought about the Aaron Rodgers "Discount Double Check" move or even waving the left hand like Beyoncé in "If You Like It."

He settled on Psy's "Gangnam Style," dancing his way off the green as the crowd roared. Two days later, the YouTube views were approaching 200,000 hits.

"I can't believe that I did that," Hahn said. "It's bringing the fun back into golf, especially with me being a rookie. It gives me a little breathing room, an ice-breaker for me and a welcome. Whether you guys hear from me, if this is my last event or if this is the first of 100 press conferences, it's all a fun experience for me."

THE LONG AND SHORT OF IT: The U.S. Open at Merion will be the shortest course for a major championship in eight years.

USGA executive director Mike Davis said Merion, which has not hosted a major since 1981, will be 6,992 yards on the scorecard. The last major course that was under 7,000 yards was Shinnecock Hills for the 2004 U.S. Open, which played 6,996 yard. Merion will be the shortest since Southern Hills, which was 6,973 in 2001.

Retief Goosen won both those U.S. Opens.

"Merion is just this wonderful blend of short and long holes," Davis said at the USGA's annual meeting. "By the time you walk off the fourth green, you're done with the par 5s. ... I think it's going to be unique in the sense that you are going to see many more birdie opportunities at Merion than you are going to see at most any other U.S. Opens. But also, there are some critically tough holes at Merion."

It's small in other ways.

The USGA decided to cut down on tickets because Merion, located near Philadelphia, is not a big piece of property like Bethpage Black or Pinehurst. The USGA will take a financial hit compared with other venues, but it felt it was worth it.

"We felt this is the right thing for the game of golf, to bring it back to a straighter test and let's see," Davis said. "So in my view, it's short. But it's a fabulous test of golf."

DIVOTS: David Duval makes his first start of the season at the Pebble Beach National Pro-Am with an old look. Nike announced it has signed Duval to an endorsement deal. Terms of the contract were not disclosed. Duval was the first player to win a major championship with Nike clubs at the 2001 British Open. Duval's only status this year on tour is as a past champion. ... Luke Donald (No. 3), Adam Scott (No. 7) and Graeme McDowell (No. 19) are the only players from the top 20 in the world ranking who have not played a tournament this year. ... The Canadian Women's Open will be looking for a new title sponsor after CN announced a chance in its golf involvement. CN instead will expand its sponsorship of Canada's national junior golf program. ... The Scottish Open will be the first regular European Tour event to be shown live on an American network. NBC Sports plans to show 2 1/2 hours of live coverage from the final two rounds at Castle Stuart to complement Golf Channel coverage. A Golf Channel spokesman says the European Tour has agreed to push back starting times on the weekend because of the five-hour time difference.
